Safecat has a difficult license that makes _assumptions_ on how DJB has
licensed his code that Len Budley took into safecat, when in fact DJB
hasn't issued a license at all; and may be a possible copyright
violation.

Maildircmd, being distributed as a patch against DJB's original
serialmail package, doesn't suffer this problem.

Also note that while Len Budley touts safecat as being really safe, but
has still not implemented a bullet-proof mechanism to generate file
names that are guaranteed to be collision free. It works today, but may
not work on a faster computer or after an OS update on a fast computer.
